Servomotors 1FK7

Servomotors 1FK7

1FK7 motors are permanent magnet excited synchronous motors which are available in the versions Compact, High Dynamic and High Inertia.

The self-cooled motors are characterized by superior overload capability, ruggedness and compactness.

The connection via rotatable connectors and preassembled cables ensures a flexible, fast and safe connection to the converter.

1FK7 Compact (CT)

  • The universal motor for a wide range of applications.
  • Space-saving installation through very high power density.
  • Large range of motors in the shaft heights 20 to 100.
  • Preferred types with short delivery times are available.

1FK7 High Dynamic (HD)

  • The sprinter in the ramp-up time
  • Very high acceleration capability due to low rotor moment of inertia.
  • For highly dynamic applications with low load moment of inertia.

1FK7 High Inertia (HI)

  • Docile control behavior with superior load inertia due to the high intrinsic moment of inertia.
  • Reduced expenditure for controller optimization.
  • Particularly suited for machine tools for feed axis applications requiring superior resp. alternating load inertia..
